In sum, the method have the advantages that
1, the volume of air flow chamber is not only reduced in the setting of the application structure, and form rule leads flow path, it is to avoid eddy current, and to the greatest extent
Hot-fluid is derived by fast guidance quality ground, shortens heat residence time in motor, and adds the fan drain of the first drain aerofoil
With strong points, drain is fast, and can guarantee that again the convenient installation of bearing, casing rigidity height and rotating shaft stable connection.And tilt to strengthen
Putting hole slot wall to offer to stator, the heat on thermal source can the most directly be derived by the first drain aerofoil, and constantly by circuit board
Outer cold air is pumped into motor inner equilibrium air pressure, and therefore heat is not only difficult to flow to circuit board direction, also can constantly have cold sky
Air-flow, through circuit board, is lowered the temperature to circuit board.
2, the vicarious stress equalization of the application, will not produce bending, and the bearing being positioned at rotor both sides has supported rotating shaft well
Distorting stress, rotating shaft running accuracy is high.And the part positioning end of the application is high with the perpendicularity of axial line, accurate positioning, axle
Shaft strength will not be made when holding pretension uneven and affect the life-span of bearing, improve the rigidity of main shaft.The housing of the application, plastic packaging
Being connected between body, base, rotating shaft firm, twisting resistance is strong, and intensity is high, and its stability is good, shakes little, more quiet, and whole electricity
Machine globality is strong, compact conformation, easy accessibility, low cost.
3, the structure of the application is particularly suitable for the motor of external stator inner rotor core, carries out thermal source quickly pointedly
Heat radiation.
4, by cross section card article triangular in shape and the setting of the spacing anti-rotation groove of shape.Base plate is carried out by sagittal plane
Location, prevents base plate from deflecting.Improve the connective stability of bearing and rotating shaft.And the structure design of triangle is spacing reliably in guarantee
While make again easier for installation, import quickly.
5, the inclination reinforcement of the application is put hole slot wall and is set strip passage, and arranges many most radially, significantly
Add airflow amount, accelerate heat radiation.Strip passage is arranged in the middle part of cell wall and length is less than cell wall by bottom land to notch
Length, it is ensured that install strengthen ring recess intensity.
6, the application compact conformation, each parts stable connection, it is adapted to the running of high rotating speed, has again the effect of rapid heat dissipation simultaneously concurrently
Really, service life is long.
7, the safety guard of band opening and the setting of antitorque gusset, improve fan antitorque with what rotating shaft together rotated
Intensity, improve two all between bonding strength, it is ensured that when running up, fan the most effectively runs, and uses safer, dissipate
Thermal effect is good.
